Cat® Counter Valve is used to prevent the attachment from dropping or running away in case of hose failure or pump stoppage. A counter valve has a check valve that allows free flow into the actuator, and a relief valve that blocks the reverse flow until it senses a pilot pressure from the directional control valve. This way, the attachment can be safely held in position without drifting or falling and improve the motion control and efficiency of the attachment. Cat® Counter Valve can regulate the speed and smoothness of the attachment movement, especially when lowering a load or dealing with overrunning loads. It can also reduce the power consumption and heat generation of the hydraulic system by lowering the pressure drop across the directional control valve. It allows quick connection and disconnection of the attachment under pressure. Cat® Counter Valve can save time and hassle, as well as reduce the risk of oil leakage and contamination. Cat® manufactures its relief valve with strict quality control and testing procedures. It meets or exceeds the industry standards and your expectations.Application:Cat® Counter Valve is used in hydraulic systems of coupler in Cat® Machines.
